The ship has been lying on its side, half submerged and perched on two underwater mountain peaks, since it crashed in January 2012, killing 32 people.

At 9 a.m. this morning, workers in Italy began the "parbuckling" process, using pulleys and steel cables to slowly pull the 60,000-ton ship into an upright position. By 5:40 p.m. local time, the ship had been dislodged from the reef and rotated 10 degrees.

In the evening, parbuckling was suspended for an hour for maintenance work. The process has resumed.

The ship will likely be disassembled where it lies, at huge cost to the local environment, a nationally protected marine park and coral reef.

At around 2 p.m. local time, Titan Micoperi, which is conducting the operation, announced "evidence of a smooth rotation movement of the hull, with a consequent rotation of about 3 degrees."

Over the past year, workers attached enormous, hollow steel boxes called sponsons to the exposed side of the Costa Concordia. If the ship is successfully parbuckled, more will be fixed to the side that is now submerged. Together, they should create enough buoyancy to keep the water-filled vessel afloat. Then it will be towed away and cut up for scrap.

The bodies of two victims were never located, and workers may find them once the ship is righted, according to NPR.
